ARTHUR SAMUEL PIERSON, OF MORRISTOWN, NEW JERSEY.

SHUTTER-WORKER.

Specification of Letters Patent.

PatentedMarch 31, 1908.

Application filed March 28, 1907. Serial No. 365,158.

To all whom it may concern:

Be it known that I, ARTHUR S. PIERSON, a citizen of the United States,and residing at Morristown, in the county of Morris and. State of NewJersey, have invented certain new and useful Improvements in Shutter-Workers, of which the following is a specification such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to window shutters, and the object thereof is toprovide a simple and effective device by means of which a window shuttermay be locked in an open or closed position, or adjusted into anydesired position and locked therein.

The invention is fully disclosed in the fol lowing specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a transverse section of thebot tom part of a window frame and showing part of a shutter providedwith my improve ment; Fig. 2 a bottom plan View of the construction asshown in Fi 1 and, Fig. 3 a section on the line 83 of Fig. 1. a

In the drawing forming part of this specification, I have shown a partof the bottom portion of a window frame, comprising the bottom sill aand one side a together with the bottom portion of a shutter b and, inthe practice of my invention I form, in the bottom of the shutter sashand preferably in the center thereof, a vertically arranged mortise b inwhich is secured a sleeve 0, the lower end of which is provided with akeeper c rotatable on said sleeve and in one side of the sleeve 6 and inthe top portion thereof is a vertical slot or opening 0 and the front orinner side of the shutter b is provided with a corresponding verticallyarranged slot or o ening b and secured to the shutter is a p ate dhaving a corresponding slotor opening d at the upper end of which is aninwardly directed finger d which passes inthrough the slots or openings6 in the shutter and c in the sleeve 0, and the object of which is toprevent the turning of said sleeve in the bottom portion of the shutter.

Placed in the sleeve 0 is a vertically movable plunger 6 the bottom endof which is tapered as shown at 0 and, in practice, a screw f is passedin through the slots or openings (Z Z2 and c in the plate d, shutter band sleeve 0 respectively and screwed into the plunger 0 and the outerend of said screw is provided with a handle Secured to the bottom of thesill a of th window frame and preferably adjacent to the right handcorner thereof when viewed from the inner side of the frame is a plateIt to which is pivoted a flat arm 'i which passes through the keeper 0and is free to move therethrough, and said arm is provided withaplurality of longitudinally arranged apertures i through which thelower end of the plunger e is adapted to pass and the bottom portion ofthe keeper 0 is open to permit the plunger 0 to pass downwardly throughthe arm a.

The plunger 6 is a gravity plunger, and the operation of the device willbe readily understood from the foregoing description when taken inconnection with the accompanying drawing and the following statementthereof. When the parts of the device have been assembled as shown inFigs. 1 and 2, by raising the plunger 6 by means of the handle f 2 ofthe screwf, the shutter b may be swung into any desired position, and inthis operation the arm i slides freely through the keeper 0 and theoperation of swinging or moving the shutter may be performed also by thescrew f or the handle thereof, and when the handle of said screw isreleased the plunger 6 will drop downwardly and will pass through one ofthe holes or apertures in the arm i and the shutter 1) may thus belocked in any desired position either closed, fully opened, or at anyangle to the window frame.

This device is simple in construction and operation and comparativelyinexpensive and may be applied to any kind or class of windows having ahinged or pivoted shutter, and my invention is not limited to the exactdetails of construction herein shown and described, and various changestherein and modifications thereof may be made without departing from thespirit of my invention as set out in the appended claims.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

A window shutter having a vertically arranged non-rotatable tubularsleeve secured in the bottom thereof, a rotatable keeper mounted on thelower end of said sleeve and the bottom of which is open, an arm adaptedto be pivoted to the bottom portion of the my invention I have signed mynameinpreswindow frame and passing loosely through ence of thesubscribing Witnesses this twenty,- said keeper, a vertically movableplunger fifth day of March, 1907.

and means for raising said plunger. JAMES A. OOLLINs,
